RTV-2 mold making silicon rubber

Production mold casting wax, gypsum, concrete or resins (urethane, polyester, etc. ) 1 Excellent performance 2)High tear strength 3) Resistance to high temperature 4) Competitive price 5) Samples are available RTV-2 molding silicone rubber are generally named as two-part room temperature sulfurated silicone rubber, which features an exceptional fluidity and good operability. When mixed with 23 curing agent, they can still be operated within 30 minutes, but will be formed after 2-3 hours. With resistance to deformation, high temperature, acid and alkali, and expansion, silicon flexible molds are used for mold duplication and delicate mold making for poli crafts, resin crafts lighting and candle crafts. Features: (1) Silicon rubber for pad printing with SGS and ROSH approval (2) Curing agent arrange together as free charged (3) In liquid form and in various colors (4) With an exceptional fluidity and good operability. (5)Temperature and deformation resistance as well as low shrinkage. (6) High duplication times.
